Analog Devices Inc. AD9136 16 位双通道数模转换器

亚德诺半导体 AD9136 是一款双通道、16 位、高动态范围数模转换器(DAC)，提供最高达 2.8GSPS 的采样速率，以支持高达奈奎斯特频率的多载波产生。数模转换器输出经过优化，可以与 ADRF6720 及 ADRF670x 模拟正交调制器(AQM)无缝对接。一个可选 3 线式或 4 线式串行端口接口(SPI)供选择，允许对许多内部参数进行编程和回读。设计人员可以在 13.9mA 到 27.0mA 的典型范围上对满量程输出电流进行编程。AD9135 DAC 采用小型 88 引脚 LFCSP 封装，具有 12mm × 12mm 的占位尺寸，非常适合于无线通信、宽带通信、发射分集、多输入多输出（MIMO）、仪器仪表、自动测试设备等应用。

Designers can program a full-scale output current over a typical range of 13.9mA to 27.0mA. Available in a small 88-lead LFCSP package with a 12mm × 12mm footprint, the AD9135 DAC is ideally suited for wireless communications, wideband communications, transmit diversity, multiple input/multiple output (MIMO), instrumentation, and automated test equipment.
